Listen folks. All I am saying is that the issue is not binary.
We want the information to be binary because it makes us feel confident about our decisions.
Take depakote.
It may help your mood. But it is a fact that it may damage your liver. It is a fact that my mother has a bad liver from years of depakote use.
There are some real dangers that may be associated with the use of certain drugs. That is a fact, not psudoscience. Just like antipsychotics can dammage certain areas of the brain. That is a fact. Psychiatrists know that. It's not just the Tom Cruises.
I am under the belief that a lot of information/dangers are withheald / played down because it is percieved that the best interest of the mentally ill.
It is not a black and white issue. I don't know why people try to make it into that.

Like I said before, I like to let the facts speak for themselves. I'm an empiricist. This is one of the most convincing studies I've come across, in years. The source data are completely independent (collected for other legitimate but reliable purposes) and show highly significant statistical relationships.

Relationship between antidepressant medication treatment and suicide in adolescents.Olfson M, Shaffer D, Marcus SC, Greenberg T.
Department of Psychiatry, New York State Psychiatric Institute, College of Physicians and Surgeons of Columbia University, New York 10032, USA. olfsonm@child.cpmc.columbia.edu
CONTEXT: A decade of increasing antidepressant medication treatment for adolescents and corresponding declines in suicide rates raise the possibility that antidepressants have helped prevent youth suicide. OBJECTIVE: To evaluate the relationship between regional changes in antidepressant medication treatment and suicide in adolescents from 1990 to 2000. DESIGN: Analysis of prescription data from the nation's largest pharmacy benefit management organization, national suicide mortality files, regional sociodemographic data from the 1990 and 2000 US Census, and regional data on physicians per capita. PARTICIPANTS: Youth aged 10 to 19 years who filled a prescription for antidepressant medication and same-aged completed suicides from 588 three-digit ZIP code regions in the United States. MAIN OUTCOME MEASURES: The relationship between regional change in antidepressant medication treatment and suicide rate stratified by sex, age group, regional median income, and regional racial composition. RESULTS: There was a significant adjusted negative relationship between regional change in antidepressant medication treatment and suicide during the study period. A 1% increase in adolescent use of antidepressants was associated with a decrease of 0.23 suicide per 100 000 adolescents per year (beta = -.023, t = -5.14, P<.001). In stratified adjusted analyses, significant inverse relationships were present among males (beta = -.032, t = -3.81, P<.001), youth aged 15 to 19 years (beta = -.029, t = -3.43, P<.001), and regions with lower family median incomes (beta = -.023, t = -3.73, P<.001). CONCLUSIONS: An inverse relationship between regional change in use of antidepressants and suicide raises the possibility of a role for using antidepressant treatment in youth suicide prevention efforts, especially for males, older adolescents, and adolescents who reside in lower-income regions.

Antidepressant medication and suicide in Sweden.
Carlsten A, Waern M, Ekedahl A, Ranstam J.
Department of Social Medicine, University of Goteborg, Sweden. anders.carlsten@telia.com
OBJECTIVE: To explore a possible temporal association between changes in antidepressant sales and suicide rates in different age groups. METHODS: A time series analysis using a two-slope model to compare suicide rates in Sweden before and after introduction of the selective serotonin reuptake inhibitors, SSRIs. RESULTS: Antidepressant sales increased between 1977-1979 and 1995-1997 in men from 4.2 defined daily doses per 1000 inhabitants and day (DDD/t.i.d) to 21.8 and in women from 8.8 to 42.4. Antidepressant sales were twice as high in the elderly as in the 25-44-year-olds and eight times that in the 15-24-year-olds. During the same time period suicide rates decreased in men from 48.2 to 33.3 per 10(5) inhabitants/year and in women from 20.3 to 13.4. There was significant change in the slope in suicide rates after the introduction of the SSRI, for both men and women, which corresponds to approximately 348 fewer suicides during 1990-1997. Half of these 'saved lives' occurred among young adults. CONCLUSION: We demonstrate a statistically significant change in slope in suicide rates in men and women that coincided with the introduction of the SSRI antidepressants in Sweden. This change preceded the exponential increase in antidepressant sales.

There is a brief increase in suicidal risk from SSRIs. When compared to that induction caused by tricyclics, it is a smaller risk. What has happened is that the SSRIs are getting bad press, that tricyclics, for example, never faced.

> LinkadgeThat's where I disagree absolutely. Antidepressants are tools. When those tools are not properly managed, I would focus on the mismanagement. The idea that a potentially suicidal depressed patient is written a prescription for one of these drugs, and told to come back in three months (or whatever), is where the problem lies. Proper medical management requires much more than that. E.g. explicit warnings to the patient, to immediately report certain specific adverse effects; frequent reassessments by trained medical personnel; involvement of the family or close friends of the patient, for monitoring purposes; brief prescriptions initially, until the patient's response can be assessed.....so much more can be done, to make the use of these drugs safe.
The medications in question are powerful, complicated, and somewhat unpredictable. The treated patients are not inherently stable at the time of treatment. Complacency in management of these medications is the primary flaw, IMHO.

I see no significant relationship.
I quote from a study in the Archives of General Psychiatry of all U.S. suicides between 96-98.
http://archpsyc.ama-assn.org/cgi/content/abstract/62/2/165
"The overall relationship between antidepressant medication prescription and suicide rate was not significant."
Most psychiatrists agree that the only agents that have demonstrated a clear effect on suicidiality are lithium and clozapine.
>It's been argued, but from smaller samples. Type >1 error is the biggest issue for scientists to >manage.
I don't see anything conclusive here.
Many of the Brittish records show an increased rate of suicide for during start up, but then little to no effect aftarwards.
>True. But when large studies were done, as were >just recently published, there is no such >signal. You have to consider Type 1 error.
No, I am referring to the whole course of the illness. Ie, how without antidepressants, most people recover from depression 8mos to a year. Some studies show that with treatement, it actually becomes a more chronic disorder.

There is no evidence to reach that conclusion. It is a conceivable hypothesis, but it has never been tested.
The only easily tested hypothesis which arises from this heterogeneity of SERT promoter regions is to determine if SSRI response is different under the three natural populations. It may well explain why SSRIs don't work for everybody. Or part of the why.
> Dr. Tracy argues that SSRI's cause depression and suicide.
SSRIs are depressogenic?
Suicide rates are falling.
http://www.afsp.org/statistics/USA.htmThere is one drug with extremely powerful suicidal potentiation. Alcohol. I won't waste space here, but I have all kinds of data on that.
There is no autopsy evidence for SSRI potentiation of suicide. But alcohol? Huge. Widely available, without a prescription.
> This link that I put up is research showing how lifetime depressive episodes correlate with the serotonin transporter gene. This research supports her theory that taking an SSRI (and thus lowering SERT activity) could cause depression, alcoholism etc.
No, it doesn't. It links a homozygous gene to those events. Not SSRIs.

Quite a few agents (for instance Surmontil) which have no effect on monoamine uptake, but do reduce REM sleep, are effective antidepressants.In so many words, it's like trying to construct a platypus. These pieces, these analogies, do no demonstrate that SSRIs do or do not do similar things. Those are untested hypotheses. Having an hypothesis is proof of nothing.

Native peoples used to make a special tea from twigs of red willow, to relieve pain. Following a traditional prayer and invocation, the medicine man would administer the decoction, believing that he had facilitated the transfer of the willow spirit to the afflicted party. Often, the pain went away.
Other people, with different beliefs, discovered salicylic acid in willow bark, derived a synthetic form, and made a near-bankrupt German dye chemist named Bayer very rich.
Both were effective treatments, with entirely different mechanisms.

When Szasz et al emptied the asylums, the enabling belief that permitted such a drastic change in medical management was that medication alone would suffice. But, what inevitably also happened was that contact with caregivers was totally disrupted. And this idea, that medicine through pharmacepia had reached a golden age, enveloped the entire culture. I remember Prozac hitting the front cover of Time magazine. I still have it, somewhere. Pure propaganda. Everyone bought into it. But nobody wants to take responsibility for it. That's how the Holocaust came about.

We're talking reports of over 500 pages. The raw data. And I'm convinced, just as the recent task force was convinced, that methodological deficiencies in many studies are so profound, that concluding anything about suicidal induction during the studies is questionable. The studies were not designed to collect that sort of information. The way the information was extracted from the raw data was flawed. In one study I analyzed, which suggested a six-fold increase in suicidality in adolescents using Paxil, the detailed analysis revealed that there were no suicidal gestures attributable to Paxil, and the only true suicidal act was in the placebo group. If you want to see that, I'll dig it up and show it to you.

Do you have any idea of the doses used in that study? Off the top of my head, I think it was 360 times the maximum human dose, maintained for 12 weeks (equivalent to 15 years of a human life span). And I think the hypothalamic dendrites were corkscrewed, not the receptors. I don't recall for sure.
> This is one of the studies refered to by Breggin.Who should have known better to simply generalize to people taking the drug as prescribed. There are toxic thresholds.

It's the lumping together of TCA and newer antidepressants that gives a non-significant outcome. TCAs are themselves quite toxic, and are associated with a significantly higher rate of completion.

In reply to your closing sentence, chronic recurrent depression is associated with more frequent treatment. Correlation is identical, when you invert the variables. Same magnitude, same direction.
Moreover, your thesis ignores the kindling effect. Aggressive medication protocols were developed precisely because of kindling.

But the point is that the level of the protein is reduced. If our theory of depression is that the *5-ht* reuptake mechanism is too active in depression, then this is information to suggest against it. Of course there could be compensatory changes in MAO-A, but this could also happen in patents treated with SSRI's.
>There is no evidence to reach that conclusion. >It is a conceivable hypothesis, but it has never >been tested.Scientists like to study one gene at a time. It makes sence to see if the 5-ht transporter is associated with depression or not. It's just like if you found low acetylcholinsterase in Alzeimer's disease, then it might make one rethink the model.

Yes, I would argue that they can be for certain individuals. Mood may be maintained by a very delicate ballence between serotonin and dopamine. If you get too much serotonin, I think it can cause depression. I experienced a distinct worsening of all core symptoms of depression on paxil.
>Suicide rates are falling.

I don't think that autopsy information is necessary.
>No, it doesn't. It links a homozygous gene to >those events. Not SSRIs.I realize that. It is not a direct link, but it is something that has really baffled a lot of researchers. I emailed Dave on www.biopsychiatry.com and asked him what he thought about the issue of the serotonin transporter, and some of the recent findings. He said to me, that sometimes in psychiartry you will find things that don't fit the mold. Sometimes the findings will seem to indicate the exact opposite.
SSRI's may *work* through a different mechanism alltogether. We have serotonin uptake inhibiting drugs that have no antidepressant potential whatsoever. All of the currently available SSRI's increase the activity of the gabaergic neurosteroid allopregnalone, some 20 fold.
>Or Tianeptine might work on homozygous short->short SERTs?
Well this is it. I was just more surprised by the fact that the study seemed to suggest that the most chronically depressed posessed the double short varient.

It is not an idiosyncracy. Both agents potently stimulate certain sertonin receptors. We have no problem accepting that GI effects may be due to excess 5-ht3 stimulation, but yet cannot believe that people have had perceptual disturbances consistant with excess 5-ht2a agonism ?
There are some documented cases of antidepressant induced perception disorder on www.biopsychiatry.com in addition to expert explainations of the events.

But that's not a common theory. (I've never heard it before, myself.) Rather, the integrated serotonin signal in a pathway or pathways is believed (by some) to be weaker in depression. In order to strengthen the signal, without resorting to indiscriminate serotonin release, existing signals may be amplified by extending the half-life of serotonin in the synapse. The hope is to enhance the magnitude of pre- and post-synaptic receptor response, contributing to the integrated signal across that neural network. If I recall correctly, the increase in half-life is measured in fractional seconds. That's one theory. <shrug>
> Of course there could be compensatory changes in MAO-A, but this could also happen in patents treated with SSRI's.
That's one of *my* arguments, against your theory. You can't just measure reuptake transporter protein, and fail to simultaneously measure MAO-A concentration, COMT concentration, and total serotonin released into the synapse. And then do the same with an antidepressant present. And then do it again, two weeks later. And so on.
The whole idea that SSRIs function by flooding the brain with serotonin is patently absurd. Reuptake inhibition takes place immediately, whereas physiological antidepressant response takes weeks. It couldn't possibly be the explanation.
And, for the same reasons, global excess serotonin is equally absurd.
> >There is no evidence to reach that conclusion. >It is a conceivable hypothesis, but it has never >been tested.
> Scientists like to study one gene at a time. It makes sence to see if the 5-ht transporter is associated with depression or not. It's just like if you found low acetylcholinsterase in Alzeimer's disease, then it might make one rethink the model.
Scientists must also delay promoting their pet theories until such time as they have evidence to describe the relationship between multiple variables upon which their theories rest.
Did you see the recent work on SERT polymorphism? Out of 96 subjects, they found 27 variants, 21 of which were previously unknown. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15993855&query_hl=2
In such complex systems, I simply avoid mechanistic arguments altogether. I don't even pretend to have a clue.

I meant generally. You can't project your experience without bias. It's a poor strategy because it fools you. Now, to say something can happen can be proven with but a single case. Amongst the (probably) billions of doses of SSRIs, I would argue that the most general conclusion is that SSRIs are not depressogenic.
You cannot apply that general conclusion to an individual. But that same argument cuts both ways. You cannot generalize from individual experience.
> >Suicide rates are falling.
> >http://www.afsp.org/statistics/USA.htm> But to associate this with SSRI use may not be accurate.
It's easy to use the word "may". What I would look for, though, is evidence for that anti-suicide agent that must be present for the initial thesis (SSRIs induce suicide) to be true. To argue that SSRIs induce suicide, while the evidence for a population shows an inverse relationship, requires that one demonstrate an independent variable of greater suicide reduction potential than the putative SSRI suicide inductive effect.
> >There is no autopsy evidence for SSRI >potentiation of suicide. But alcohol? Huge. >Widely available, without a prescription.

Perhaps not necessary, but informative. It makes the SSRI-suicide link look a tad anemic. 40-45% of suicides positive for alcohol. Ever seen a suicide warning on a can of beer? Just a couple of examples...
Forensic Sci Int. 2005 Jan 17;147 Suppl:S25-8.
Fatal suicide cases from 1991 to 2000 in Szeged, Hungary.Havasi B, Magori K, Toth A, Kiss L.
Department of Forensic Medicine, University of Szeged, 6722 Szeged, Kossuth L. sgt. 40, Hungary. havasi@anat-fm.szote.u-szeged.hu
The aim of this study is to analyze the fatalities due to suicide in the period of 1991-2000. The autopsy reports of 719 suicide cases during that period of the Department of Forensic Medicine, University of Szeged were reviewed retrospectively. The victim's age, sex, way of commitment, place of death, the presence of alcohol and drug influence and survival time were recorded. Five hundred and one of the (69.6%) total 719 suicide fatalities were men and 218 (30.4%) were women. The largest age groups were 41-50 in men, in women we experienced a 'double-peak' of age groups 41-50 and 71-80. The most frequent way of committal was hanging (46%). The results revealed that 38.8% of the 474 victims whose blood and/or urine alcohol concentration measurement were carried out consumed alcohol prior to the act. The presence of licit drugs in 12% of not drug-related cases were experienced.

Pathoanatomic findings and blood alcohol analysis at autopsy (BAC) in forensic diagnoses of undetermined suicide. A cross-cultural study.Ferrada-Noli M, Ormstad K, Asberg M.
Department of Clinical Neuroscience, Karolinska Institute, Karolinska Hospital, Stockholm, Sweden.
In Sweden, ca. 25% of unnatural deaths ascribed to self-inflicted injury are finally recorded as 'undetermined suicide' (abbreviated UMSA), i.e. the forensic pathologist has not been able to establish whether the fatality was an accident or a suicide. In the present study, a series of UMSA cases was investigated with the aims to study the impact of immigrant status, and alcohol abuse on the occurrence of this forensic diagnosis on the mode of death. The alcohol issue was addressed by focusing on blood alcohol concentrations at autopsy (BAC) and post mortem signs of alcohol-related organ pathology. The results can be summarised as follows: Positive BAC occurred at an equal rate in the UMSA group and in definite suicides, i.e. about 45%. Among non-Swedish UMSA victims positive BAC was more common (50%) than among the Swedish (41%), whereas no difference was found in the definite suicide group. The level of BAC at autopsy was significantly higher in Finnish immigrants than in other ethnic groups. Organic signs of chronic alcohol abuse were found in 13 of 40 cases testing positive for BAC; thus, presence of alcohol at autopsy may reflect incidental intake rather than habitual overconsumption.
> >No, it doesn't. It links a homozygous gene to >those events. Not SSRIs.> I realize that. It is not a direct link, but it is something that has really baffled a lot of researchers. I emailed Dave on www.biopsychiatry.com and asked him what he thought about the issue of the serotonin transporter, and some of the recent findings. He said to me, that sometimes in psychiartry you will find things that don't fit the mold. Sometimes the findings will seem to indicate the exact opposite.
I don't know what you mean by your closing sentence. And, I was refuting any connection between the gene findings and SSRI effects. It is petitio principii, begging the question, to accept that the SERT promoter polymorphism tells us anything about SSRIs. It certainly isn't a conclusion obtainable from the evidence presented.
> SSRI's may *work* through a different mechanism alltogether. We have serotonin uptake inhibiting drugs that have no antidepressant potential whatsoever. All of the currently available SSRI's increase the activity of the gabaergic neurosteroid allopregnalone, some 20 fold.
I have absolutely no doubt that reuptake inhibition is possibly a tiny, and perhaps even inconsequential, aspect of their mechanism of effect. I'm sure we'll keep finding more and more effects, that we never anticipated finding.
> >Or Tianeptine might work on homozygous short->short SERTs?
> Well this is it. I was just more surprised by the fact that the study seemed to suggest that the most chronically depressed posessed the double short varient.
I think it's premature to make anything out of this finding. We don't know if the gene is pleiotropic, for example.
> >I strongly reiterate. There is no pathological excess serotonin state.> I strongly reiterate. Some researchers think that excessive serotonergic function in certain areas of the brain result in anxiety.
You're starting to come off the Tracy position. The key is *localization* of the serotinergic activity. And the activity in that locality is a relative finding.

This example is nothing more than a poor explanation to a layperson.
The key point, I state for the umpteenth time, is localized serotinergic activity. There is no global excess serotonin state.
> >Getting back to how this phrase came into our >discussion, Tracy claims that this "excess >serotonin" state causes premature aging. You >seem to have just contradicted that, quite >explicitly.> I don't see what you mean.
You clipped it. You said:"If any drug were capable of mimicing some the catastrophic alterations in cognition an sentience that are evident in old age, I'd like to know about it."
If SSRIs cause this excess serotonin state, which causes premature aging (all her language), then your contention that there is no drug that could cause that certainly absolves SSRIs of any possibility of doing so, eh?
> There are theories out there as to how SSRI's may advance aging. The melatonin theory sounds convincing. I can see how chronically lowering melatonin might acellerate aging. There are other theories too.
Which is it, then? SSRIs to blame, or no drug can do it (mimic aging)?
The thing I keep having to point out, Ian, is that a theory is proof of nothing. Where are the data?
> >No, not potentiation. "...all data were >compatible with additivity of effects rather >than true potentiation."> The article says that fluoxetine substituted for LSD in certain paradigms.
You said potentiation. That is not potentiation. The dogs were preconditioned (read their normal receptor function was altered). It wasn't a naturalistic observation, this somewhat congruent drug effect.
> >The one above was about dogs. I wonder just what >the dogs said to describe their experiences.> This is about findings that may confirm some of the experiences that people have had.
I don't think it does anything of the sort.
I'll say it as often as I have to. That there are adverse events, serious adverse events, is not in question. With the billions of doses of these drugs consumed, it would be inconceivable for there not to be such events.
Do you have any idea what the death rate is from NSAIDs, each year? It exceeds the rate of suicide, from all causes, let alone from SSRIs. Context.

I believe it happens. It's uncommon. When it does happen, the offending agent may be discontinued, and relief is then sought elsewhere.

She claims blood sugar relationships to mental illness. It should be blessedly easy to come up with supporting data. Same with her magic oils. Data?

But that's empiricism. That's my point, all along. Red willow spirit mechanism arguments won't stop someone from bleeding to death due to gastric perforation.
BTW, aspirin would never make it to market today, as a prescription drug. That it is an over-the-counter remedy is a quirk of history. It is still legal today to do trans-orbital frontal lobotomies, under the same sort of grandfathering legislation.

Yes, it is a truth. Not because they have a theory. Because they have empirical evidence sufficient to convince the regulatory authorities that having the drug is better than not having it.

> Wasn't it you who requested a "Do not ECT" affixed to medical information? What are you reasons for being against ECT? Who else will people listen to. "Good" doctors don't warn against its detremental effects.
The decision was personal, and is quite the reason why informed and consent are part of the procedure before a major medical intervention. It matters not what other doctors thought, in the end. It matters what I thought. And my identity, such as it is, has formed alongside a fairly competent and powerful intellect. Any threat to that access, to recall, to partake of that identity was an unreasonable risk, for me. I would rather remain depressed than take that risk, even if later judged incompetent to make such a decision. My wishes were in writing, and enforceable. Just like a "do not resuscitate", I drew up a "do not ECT". My brain. My call.
> >If you've got the time, you can take Breggin >apart, too.
>
> YOu may be able to pick at parts of their arugments but you can never dismatle the whole.I disagree. Good science stands quite vividly, on its own. Bad science screams and dances and uses flashing lights. But when the people with the magnifying glasses show up, it just isn't there, at all. Bad science can be deconstructed using its own language. Its own logic. And its failure to show why other competing conclusions are not as reasonable, or are less reasonable, than is the bad science.
It can be a large to task to reverse the effect of well-publicized bad science. We're swamped with it. Like dietary cholesterol being a health risk. Or sodium being a heart unfriendly ion. In limited cases, these arguments hold, but for most people, health deteriorates on these guidelines.
I simply wish I had the health to do some deconstructing, and go public with the challenges that deconstruction uncovers. As I've said many times, I'm an empiricist. Show me the data. Show me how you collected them. Show me what you did to derive your stats/pattern/what have you. The science is the data. All else is human ego waving its hands to the curious or the frightened.
It is human nature to jump to conclusions. It is a scientist's job not to do so. On good data, any competent scientist will reach a fairly similar conclusion. But even competent scientists make mistakes. And I don't care if you won the Nobel prize, I'll start at your data, and your methodology, and take a look for myself.
And I play devil's advocate a lot. I don't express my own opinions, a good part of the time. That's because the deconstruction process itself reveals serious problems. I point out those problems, without even needing to reassess and come to conclusions of my own.
And, Ian, that's why I didn't listen to the whole taped interview of Dr. Tracy. I'll grant her that conceit, that honorific, one last time. When a building is constructed on weak foundations, gravity will bring it down. When a scientific theory is founded on weak (or nonexistent) data, it takes thinking people to bring it down. I challenge people to think. And I mean never to hurt feelings, though I know that I do. I'm not a perfect debater.
So, I apologize if I have crept into the personal. As I keep saying, good science stands for all to see. I needn't embellish any of that.

Or Chicken Little. They dishonour that core truth, by wrapping it in false clothes. And when the discrediting comes, the core truth may fall in the wasteheap, as well.
The reason I looked into the science of adverse effects of SSRIs arose from my own experience. I experienced psychotic dysphoric mania on an SSRI. My complaints fell on deaf ears. My repetitive cries that sleep grew harder to obtain, until I stopped sleeping altogether, were ignored. And then Serzone, nearly killed me in just 11 days.
But when I looked at the "science" presented by the Tracy/Breggin crew, there was a sheep in wolf's clothing. (note the inversion)
And no matter how much credit people want to give to the Tracys and Breggins, it was the Healys who did the job. They lobbied with real data, hard science, and the re-examination began.
My experience teaches me. I don't blame the drugs. I asked for them. And they were provided to me, in good faith.
I don't expect anyone to agree with my position. I do ask that it be considered. I join in the debate.
And the chips fall, hopefully, with nothing more revealed, at the end, than the science. The empirical evidence.
Have you heard the phrase, "the more you know, the less you know", or some variant? I think it's from the awareness of how much of what we collectively think we know is no more than a tissue of conjecture. It makes me want to be back in the lab, recording data. <sigh>

Tracy says SSRIs kill, via suicide. SSRI presciption rates have skyrocketed. This implies?
We look at available data, independently collected by reputable scientists for reputable motives, and we do not see the implied signal.
To the stats. Correlation is not evidence of causation. I would argue that it does imply it, based on my perception of human nature.
However, correlation has four categories of explanation.
1. Some variable A leads to some measurable change in variable B.
2. Some variable B leads to some measurable change in variable A.
3. It was a fluke. There is no relationship between A and B, but you measured a group unrepresantative of the greater population.
4. Some unmeasured variable C, leads to measurable change in both variable A and variable B.This is where the tough thinking begins. Hypotheses form. The thing is, the first 2 cases are indistinguishable. It doesn't matter how you graph them (which variable is the arbitrary independent variable, on axis X, and which is the dependent, graphed on Y), the very same coefficient of correlation will be obtained, with indentical significance.
What most people also fail to consider, even when numerous experiments have narrowed it down to e.g. A probably causes B, you can never exclude the fourth explanation.
Scientists do, however, love to assign probability to their data, i.e. the probability that their data is not a fluke observation.
It is my opinion that the probability that there has been a net suicide increase due to SSRI exposure is close to nil. Unfortunately, tragedies have occurred. And I will always be saddened by that realization. I think we have let people down. I pray we bring all our resources together to prevent all that we can. By looking at all available data, we now know when the vulnerable periods are.

It could not be more relevant.There was a study done in Utah, which has the dubious distinction of having the highest prescription rate for SSRI antidepressants. The blood from 49 adolescent suicide victims was analyzed. Not one of the subjects had detectable SSRI in their blood. However, 24% of the youths were prescribed these drugs. What is the perception (without knowledge found at autopsy)? And how does it differ from fact?

I am just questioning what kind of data may be collected, and I don't see how an autopsy would disclude a link between SSRI's and suicide since the death may not be an overdose of SSRI's.

> But I am wondering what you mean by autopsy indicating SSRI potentiation of suicide?
I'll rephrase. We can compare population exposure to a substance, and autopsy evidence for exposure to a substance, and see if the incidences differ.
The idea that SSRI exposure somehow leads to suicide is testable.
Tracy suggested that was the case. If SSRIs potentiate suicidal thinking and acts, we'd observe disproportionation at autopsy.
> Is it routeen for a person who has killed themseves with a gun to be tested for levels of antidepressants in their system ?
Absolutely not. (Except in parts of Scandinavia. They document everything.) But the question was asked. And some medical examiners have looked. They recorded the data, and gave summary statistics. The pattern in those statistics is inconsistent with an SSRI-triggering theory.
> I am just questioning what kind of data may be collected, and I don't see how an autopsy would disclude a link between SSRI's and suicide since the death may not be an overdose of SSRI's.
>
> LinkadgeOverdose of SSRIs seldom leads to death. So seldom, that it is reported in case report form in medical journals. But the very presence or absence of SSRI drugs in known suicide may reveal important relationship-type data.
We look to toxicological data, such as exposure to e.g. cocaine, alcohol, amphetamines, neuroleptics, antidepressants, marijuana, and so on, in a series of confirmed suicides. Method of suicide is not considered. The blood evidence for exposure to drugs, etc. is simply listed. Then, we can compare this suicide population, to the general population, based on known exposure patterns. And, what we find is an under-representation of proven SSRI exposure in known suicides. Alcohol exposure runs at about 40%, give or take, in known suicides. Just as a contextual element, I raise alcohol exposure.
Here's a sample of the SSRI data.

Selective serotonin reuptake inhibitor antidepressants and the risk of suicide: a controlled forensic database study of 14,857 suicides.Isacsson G, Holmgren P, Ahlner J.
Neurotec, Division of Psychiatry, Karolinska Institute, Stockholm, Sweden. goran.isacsson@neurotec.ki.se
OBJECTIVE: To test the hypothesis that selective serotonin reuptake inhibitor (SSRI) antidepressants may have a suicide emergent effect, particularly in children and adolescents. METHOD: Detections of different antidepressants in the forensic toxicological screening of 14 857 suicides were compared with those in 26,422 cases of deaths by accident or natural causes in Sweden 1992-2000. RESULTS: There were 3411 detections of antidepressants in the suicides and 1538 in the controls. SSRIs had lower odds ratios than the other antidepressants. In the 52 suicides under 15 years, no SSRIs were detected. In 15-19-year age group, SSRIs had lower relative risk in suicides compared with non-SSRIs. CONCLUSION: The hypothesis that treatment of depressed individuals with SSRIs leads to an increased risk of suicide was not supported by this analysis of the total suicidal outcome of the nationwide use of SSRIs in Sweden over a period of 9 years, either in adults or in children or adolescents.

Isacsson G, Holmgren P, Druid H, Bergman U.
Department of Clinical Neuroscience and Family Medicine, Huddinge University Hospital, Sweden. Goran.Isacsson@cnsf.ki.se
BACKGROUND: Systematic clinical investigations of consecutive suicides have found psychiatric disorders in 90-95% of subjects (depressive disorder 30-87%). AIMS: To investigate use of psychotropics in men and women of different ages who commit suicide. METHOD: Results of toxicological screening in 5281 suicides in Sweden 1992-94 were studied. RESULTS: Psychotropics were detected in 45.3% of the suicides. Antidepressants were detected in 12.4% of the men and 26.2% of the women (7.2% and 14.2%, respectively, of those under 30 years of age). Neuroleptics or antiepileptics (in the absence of antidepressants) were detected in 8.3%, and anxiolytics/hypnotics alone in 20.5% of the subjects. Overdose by an antidepressant was the probable cause of death in 2.1% of the men and 7.9% of the women. CONCLUSIONS: The pattern of psychotropics detected in toxicology was incongruent with the pattern of diagnoses found in the clinical investigations of suicides mentioned above. Depression appears to be under treated in individuals committing suicide, especially in men and in subjects under 30 years of age.
Just for its thought-provoking capacity, I present the following. There is a powerful correlation between homicidal violence and vegetable oil consumption (dominant source of omega-6 fatty acids). Just look at that correlation coefficient (r = 0.94) and the significance (P < 0.00001). That's less than 1/1000th of 1% chance the observation is a fluke, with 88% of the variation (r squared) attibutable to this variable.Makes me wonder much more about diet than drugs.

Lipids. 2004 Dec;39(12):1207-13.Increasing homicide rates and linoleic acid consumption among five Western countries, 1961-2000.

Laboratory of Membrane Biochemistry and Biophysics, National Institute on Alcohol Abuse and Alcoholism, National Institutes of Health, Bethesda, Maryland 20892, USA. jhibbeln@mail.nih.gov
Clinical intervention trials and animal studies indicate that increasing dietary intakes of long chain n-3 FA or reducing linoleic acid intake may reduce aggressive and violent behaviors. Here we examine if economic measures of greater n-6 consumption across time and countries correlate with greater risk of homicide. Linoleic acid available for human consumption was calculated from World Health Organization disappearance data for 12 major seed oils in the food supply for the years 1961 to 2000 in Argentina, Australia, Canada, the United Kingdom, and the United States (US). Homicide mortality rates, adjusted for age, were obtained from the central judicial authority of each country. Apparent linoleic acid intake from seed oil sources ranged from 0.29 en% (percentage of daily food energy) (Australia 1962) to 8.3 en% (US 1990s). Greater apparent consumption of linoleic acid correlated with higher rates of homicide mortality over a 20-fold range (0.51-10.2/100,000) across countries and time in an exponential growth regression model (r = 0.94, F = 567, P < 0.00001). Within each country, correlations between greater linoleic acid disappearance and homicide mortality over time were significant in linear regression models. Randomized controlled trials are needed to determine if reducing high intakes of linoleic acid by seed oils with alternative compositions can reduce the risk of violent behaviors. These dietary interventions merit exploration as relatively cost-effective measures for reducing the pandemic of violence in Western societies, just as dietary interventions are reducing cardiovascular mortality. Low linoleate diets may prevent behavioral maladies that correctional institutions, social service programs, and mental health providers intend to treat.

The reason that these intial stuides were done, was to try and find a link between the activity of SERT and depression. I am guessing that researchers hoped to find the opposite.
Researchers like to test certain suspect genes at a time. The study shows an association. Of course it does not *imply* that low activity of SERT causes depression, but it reveals an association.
What is surprising researchers is the direction of the association. If the low serotonin theory is true, and you have low activity of sert in depression, than you would require a even more significantly high activity of MAO-A, in order to maintain overall low serotonin. I supose that these individuals with low SERT may have extrordinarily high MAO-A. But it still goes to show that we may be attacking the system from the wrong angle. I mean if you want to make these individuals brain chemistry resemble that of a normal individual, does it make sence to push SERT activity down even further below the already low levels with an SSRI ?

Perhaps they may cause compensentory changes with the 5-ht system. Downregulation of 5-ht2 receptors? That can be done with 5-ht2a antagonists, surprisingly. It can also be done with melatonin, which acts functionally as a 5-ht2a antagonist. It may just be a consequence of normalized HPA axis function. Surmontil produces the same adaptive changes in receptor systems as other tricyclic antidepressnats, yet has no effect on monoamine uptake. So I argue, if serotonin uptake is unneccesary, might tampering with it cause problems ?

Like I said, it depends on who you talk to. This board is full of acounts of antidepressants making certain peoples depression worse. Another argument I have is that they may worsen the course long term. For many, they cause insomnia for the duration of treatment. This may lead to more depressive symptoms long term.

I realize that. But we know that antidepressants only work for a fraction of patients. There are many reports of antidepressant drugs worsening depression.

It wasn't my closing sentence. Basically, I was under the impression that Dave was agreeing with me that some of the findings are baffling in terms of our current theories about what may be wrong.

I think it is a great place to start. It indicates to use that the system is much more complex than the drug commercials make it out to be. It forces researchers to continue to reevaluate the theories. But most importantly, it leaves the door "open" to explainations as to why things can go awry with the drugs' use.
>You're starting to come off the Tracy position. >The key is *localization* of the serotinergic >activity. And the activity in that locality is a >relative finding.I see your argument has reformed too. The thing is this. SSRI's do not discriminate. They affect serotonin in the good parts of the brain, and the bad parts of the brain. If we have evidence to suggest that high serotonin activity in certain parts of the brain may lead to anxiety, then we have a start to understanding why SSRI's can make many peoples anxiety much worse. Tracy's argument is perhaps an overgeneralization. But it is a not completely inacurate. And no more simplistic than the drug comercial's proposed statements "anxiety is related to low serotonin".
>This example is nothing more than a poor >explanation to a layperson.
The drug companies try to fit things into a box too. They try to convince the public that it is all due to low serotonin, and that zoloft will fix it. Even if Tracy's arguments serve to stir the pot, and get people to look further into the issue, then I see it as a good thing. When she says that anxiety may be related to elevated serotonin, then this is not a lie. *Of course* we are reffering to a portion of the brain, but then so are *all* comments made about low serotonin being implicated in these states.
>There is no global excess serotonin state.
Ok, fine. That word "global" gets you away with a lot. But her arguments are with respect to the propensity of SSRI's to create some of the problems for which they are marketed to solve. Under that premise, information relating high serotonin in certain brain regions to say, anxiety, fear etc, become very relavant.
>If SSRIs cause this excess serotonin state, >which causes premature aging (all her language), >then your contention that there is no drug that >could cause that certainly absolves SSRIs of any >possibility of doing so, eh?
Your misunderstaning. I am referring to the fact that she brough the issue up. I am speaking about the relavance of the topic as if I was an uninformed listener. If the drugs cause (/the notion that the drugs cause) premature aging, is of importance to the patient.
>Which is it, then? SSRIs to blame, or no drug >can do it (mimic aging)?I think you are trying to define premature agining so stringently that the drugs could never fit the definition. Of course premature aging can not be completely defined, because we don't even know what causes agining. But in the sence long term use may create prematurely a number of symptoms associated with aging, it is not an unfathomable concept.
>The thing I keep having to point out, Ian, is >that a theory is proof of nothing. Where are the >data?
You are right. We are devoid of many long term studies on the safety of SSRI's. That is a big problem. Just like we don't really have many studies on the issue of "antidepressant poop out". I am sure you are able to accept the presence of antidepressant poop out, for instance, without a randomized double-blind, placebo controlled study indicating it occurs. If somebody got on the radio and said antidepressants poop out occurs, I wouldn't scoff the notion based on the absence of stringent trials. It is important to use our eyes and ears too.

Potentiation. When the drug, fluoxetine, is capable of enhancing some of the effects that are characteristic of hallucinogens.

Fortunately you never had to take these drugs while your brain and body was still developing. It is a time when you don't really know what is normal and what is not. As a teenager given SSRI's, it was very difficult to decide what was supposed to be normal. The severe GI disturbance I had, I thought was just related to psychosocial stress.

Evidence for efficacy does not equate to proven theory, and a theory that has not been proven, is unproven.

We have discovered that they work sometimes. We have discovered that oftentimes they perform worse than placebo. We have discovered that often times we need 8 trials to show the drug performs better than the placebo. Those are truths.

Like I said before. I don't agree with everything she says, just the pieces of information she brings up that have truth to them. Like for instance the fact that a drug company can repeatedly test a drug without ever having to disclose the failing results.
>The data are the science. I verified the data. >The faulty summaries are not the science.
I can't see how you call those who reach other conclusions faulty. You saw, for instance a correlation between SSRI use, and the marginal reduction in suicide rates over the past few years. Others look to see that suicide rates have been this low before in the past 50 years and that the minimal decrease may be related to something else. There are different ways to interprate see the same data.
>The argument in support of these drugs is >empirical. Raw statistical data for efficacy.

I am sorry. Just doing a simple Google search on the topic it is easy to see that there many different oppinions, and many different stances.
I am sorry you are resorting to binary tactics again. Struggle? When? Where?Different people, different conclusions. The Brittish decided to impose their prescribing restrictions not just based on the possability of increased suicide risk, but also based on what they saw as a general lack of proven efficacy of the drugs in this age group.
>My apologies, for failing to use the >word 'recent', i.e. last six years, and some >earlier stuff.
Even that is a meaningless statement, because it depends on what you deem to be "the topic". And yes there are studies that you have not read, namely the ones that the drug companies are under no obligation to publish.

Drugs that cause immediate increases in synaptic serotonin concentration, e.g. Ecstacy or powerful agonists e.g. LSD, stand in somewhat stark contrast from the serotonergic antidepressants, which take weeks for most of the effects to appear. (There are exceptions, but I'm just wanting to make a simple point.) So, serotonin receptor mediated events that lead to changes in regulatory behaviour in the neuron are most likely what makes an antidepressant an antidepressant.
I once posted an overview of changes in RNA concentration following antidepressant exposure. There were many dozens of significant changes, up to 20-fold. Just looking at permutation, we're already being forced to consider something like 10^17 possible meaningful interactions of those changes. I wish I could think of what the paper was called.
That's why I go back to empirics. We put this drug into a mysterious processor, and we observe these common outputs. How, why, why not.....I'll never pretend to know.

Comment in:
J Clin Psychiatry. 2002 Feb;63(2):168.Incidence of sexual dysfunction associated with antidepressant agents: a prospective multicenter study of 1022 outpatients. Spanish Working Group for the Study of Psychotropic-Related Sexual Dysfunction.
Montejo AL, Llorca G, Izquierdo JA, Rico-Villademoros F.
University Hospital of Salamanca, Psychiatric Teaching Area, University of Salamanca, School of Medicine, Spain. angelluis.montejo@globalmed.es
BACKGROUND: Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), venlafaxine, and clomipramine, are frequently associated with sexual dysfunction. Other antidepressants (nefazodone, mirtazapine, bupropion, amineptine, and moclobemide) with different mechanisms of action seem to have fewer sexual side effects. The incidence of sexual dysfunction is underestimated, and the use of a specific questionnaire is needed. METHOD: The authors analyzed the incidence of antidepressant-related sexual dysfunction in a multicenter, prospective, open-label study carried out by the Spanish Working Group for the Study of Psychotropic-Related Sexual Dysfunction. The group collected data from April 1995 to February 2000 on patients with previously normal sexual function who were being treated with antidepressants alone or antidepressants plus benzodiazepines. One thousand twenty-two outpatients (610 women, 412 men; mean age = 39.8 +/- 11.3 years) were interviewed using the Psychotropic-Related Sexual Dysfunction Questionnaire, which includes questions about libido, orgasm, ejaculation, erectile function, and general sexual satisfaction. RESULTS: The overall incidence of sexual dysfunction was 59.1% (604/1022) when all antidepressants were considered as a whole. There were relevant differences when the incidence of any type of sexual dysfunction was compared among different drugs: fluoxetine, 57.7% (161/279); sertraline, 62.9% (100/159); fluvoxamine, 62.3% (48/77); paroxetine, 70.7% (147/208); citalopram, 72.7% (48/66); venlafaxine, 67.3% (37/55); mirtazapine, 24.4% (12/49); nefazodone, 8% (4/50); amineptine, 6.9% (2/29); and moclobemide, 3.9% (1/26). Men had a higher frequency of sexual dysfunction (62.4%) than women (56.9%), although women had higher severity. About 40% of patients showed low tolerance of their sexual dysfunction. CONCLUSION: The incidence of sexual dysfunction with SSRIs and venlafaxine is high, ranging from 58% to 73%, as compared with serotonin-2 (5-HT2) blockers (nefazodone and mirtazapine), moclobemide, and amineptine.

Maybe. Placebo response is the bugbear of mood disorder treatment. Placebo response in e.g. positive symptom schizophrenia is estimated at < 3%. Here is an excellent article about the difficulties in interpretation that arise because of the clinical trial system for medication being inappropiate for mood disorder treatments.

You've confused me again, with your parenthetical remark. Nothing was proven, but it would be prudent for me to avoid that drug, in future.

In your words, n is an important factor. If this idea has not been tested widescale, then its not much good to us yet. Of course it is testable, but when larger studies come in I may be more convinved.

But if levels of antidepressants are not a routeen check, then an association has not been proven conclusvely. Small studies showing a lack of association don't mean a whole lot.

I am not arguing that isn't a testabe hypothesis. I am aruging that it hasn't been tested sufficantly.
>OBJECTIVE: To test the hypothesis that selective >serotonin reuptake inhibitor (SSRI) >antidepressants may have a suicide...This type of study is great, although this type of research is preliminary. The study came at a convenient time. I would need to see more studies of this type to conlcude anything. It also doesn't adress the fact that the drugs may indeed induce suicidality without resulting in suicide. People under medical care, also may be less likely to actually complete the act. It is fully possable that the drugs create the desire to die without triggering the act.
>Psychotropics and suicide prevention. >Implications from toxicological screening of >5281 suicides in Sweden 1992-1994.
There is another problem with these studies. They are testing levels of antidepressants within the blood of suicide victoms. This type of study is not geared to reveal any great association because you have a large group of untreated people pooled in which may downplay an association. There needs to be a double blind trial comparing suicidal tendancies induced by placebo vs. active SSRI.
>Increasing homicide rates and linoleic acid >consumption among five Western countries, 1961->2000.Thats great. This points to the idea that dietary deficiancy or functional deficiancy of n-3 polyunsaturated fats may lead to increased suicide. I don't know, does Tracy recommend elminating omega 3 in favor of O-6 ?

You are mixing two aguments. I am familliar with the proposed mechanisms of SSRI's, and I still contend that the observed cases of SSRI related visual disturbances are related to a LSD like serotonin agonism. SSRI's can act as potent agonists at all serotonin receptors.

When you have a drug that is oftentimes performing no better than placebo, you'd better make sure it is safe. Thats what sparks this contoversy, the combination of questionable efficacy, and questionable safety.
>Exactly. Perhaps I did. It certainly took place. >The role of Luvox is not clearly defined.I believe you know yourself well enough to distinguish. For me it is simple, sinusoidal head movements, head twisting sensations, severe ballance problems, and a whole host of co-ordination problems usually resolve within 4 hours of taking zoloft or celexa.

Those weren't small studies, and the null hypothesis was accepted. The alternate was rejected. Not by opinion, but by hypothesis testing (statistical analysis).

It was a retrospective study of existing information. I don't know what could be more informative.

Did you read the full-text studies I linked with? The third one answers that question.

No, it shows that excess omega-6 leads to homicidal violence.

Dude, Tracy recommends these oils:
http://www.essentialoiltherapies.com/prodInfo_blends.html
Refer back to my first post in this thread, and go to the quotations numbered 16 and 18. Her treatment is called aromatherapy. These are not dietary fats.
Nothing against aromatherapy, but it isn't going to heal serious mental illness.
And, by the way, sesquiterpene oils rubbed on the feet do not clear that gummy gooey stuff out of the brain, as she claims.
I'm done with this thread.

Fine. Let's just keep using tricyclics, which on every measure, come up worse than SSRIs.
> I don't think you have bipolar disorder, do you ?No, I do not. Unless you accept other nosologies, where AD-induced mania is a form of bipolar.

From the first of those two:
"In comparing fatal suicide attempts, we did not detect any differences between SSRIs and placebo (0.95, 0.24 to 3.78). "From the second one:
"The pooled odds ratio (with 95% credible intervals) for all SSRIs compared with placebo treated subjects in relation to suicide was 0.85 (0.20 to 3.40)."Considering that a clinical trial seldom exceeds 10 weeks, and the critical danger period for suicidal act is most definitely within these ten weeks, the failure to discover any evidence for an increase in suicide would tend to fail to support your/Tracy's hypothesis. One could fairly argue that the SSRIs were modestly protective against suicide.
